Hi Billy. There are a number of good industrial footwear suppliers in the UK and their products are quite wide and deep at the toes, giving room for orthotics if the foot is not too distorted. If you do a search for Industrial footwear you will see a number of good manufactures that I recognise. Spend about £50 - £70 for something decent.
Sometimes the only option is made to measure but the cost can be prohibitive. We only get asked to do it in exceptional cases because the off the shelf provision is so good. If you need to go that route then look at the 20 or so members of shoemakers network. http://www.shoemakers.org
